World Car Fans rounds up the next bunch of AMG-model Benzes spied in prototype form. They've compiled the latest shots of the C 63, GL 63, R 63 and CL 63 AMGs — all due by 2007 — caught during various manner of preproduction testing. The common thread is the new 6.2-liter V8 — AMG's first ground-up engine product — that will provide naturally aspirated gumption to nearly the entire line (over 7G-Tronic Speedshift trannies). With one-in-20 Mercedes models sold in the US an AMG product, it's no secret the Merc division is expanding its profile. Now all we need is six extra figures in disposable income and clear highway and a well-connected traffic-court lawyer.
